## Overview

The BWidget package is a library extension for Tcl/Tk versions 8.1.1 or higher, written in pure Tcl/Tk code. Its download location is

Tablelist supports interactive cell editing with the aid of the Entry, SpinBox, and ComboBox widgets from the BWidget package. The steps needed for using one of these widgets for editing the cells of a given column are as follows:

1. Register the desired widget for interactive cell editing by invoking one of the commands described in this reference page.
2. Use the tablelist widget's `columnconfigure` subcommand to set the given column's `-editable` option to true and its `-editwindow` option to the value returned by the command mentioned above. (These options are supported at cell level, too, with the aid of the `cellconfigure` subcommand.)

REMARK: The temporary embedded BWidget widget used for interactive cell editing will appear properly scaled, according to the display's DPI scaling level, given by the variable `tablelist::scalingpct`.
